To all euhom it may concern:

l 3e it known that I, JOHN P. Gnosn'r, a citizen of the -United States,residing at Bothell, in the county of King and State of Washington, haveinvented certain new and useful Improvements in "Ice-Cream-Cone CookingMachines, of which the following is: a specification.

This invention relates to cooking machines: and has particular referenceto machines of the type illustrated and described in my prior Patent No.1,010,619, issued December 5, 1911. v

The object. of the present invention is the periectingof such machineswith a view to rendering more uniform the shaping and:-

eoolcing of the cones which are produced thereby. I

The improvements consist in the employment of heatingelements witheachgroup' of cone molds, novel devices for feeding the batter to thevarious molds, and means whereby the complementary elements of the moldsare positively maintained in suitable relative positions during theearly portions of the cooking operations.

The invention further consists in the novell construction andcombination of parts, as will be hereinafter described withreference tothe accompanying drawings, in which- Figure 1 is a transverse verticalsection of a cooking machine illustrating the invention. Fig. 2 is afragmentary plan View of the same. .FlfZSx and 4 are sectional viewstaken through 3-3 and 1- 1 of Fig. 1.

each matrix is provided apivot 16 for a disk 17 which is provided withcam slots 17' to receive pins-18 secured. to the adjacent by a rod 19with the crank pin 20v provided on a toothed pinion 21 mounted forrotary motion on the carrier. .These pinions are each provided with anequal number of teeth to that provided on the sector gear 12 so that thelatter will cause the complete rotation of each of the pinions as thesame are revo'lubly carried by the. sector teeth. As

the pinions 21 are thus affected, the disks 17 The disks 17 areeach'connected are influenced through the mediumof the rods 19 to effect theopening and closing of the respective mold matrices for the purpose 7 offirst discharging the cooked cones and then be restored into position toreceive bat. ter from the feeding devices. For cooperation with each ofsaidmatrices and consti- .tuting parts of the various molds areformermembers 22 hingedly connected bypins 14;, as shown, to the upper.ends of the studs 14,

.. Depending from each of the former'member's are hollow core elements23 arranged to enter the recesses of the respective matrix members, asshown at the right hand side of Fig. 1. Said former members aresuccessively tilted upwardly into the positions such as illustrated atthe left side of the view, just before the associated matrices areopened, and in such elevated positions the former members are'retaineduntil after the respective matrices whereupon the former members arelowered into their-original positions. The raising and lowering of theformer member is acc'omplis'hed by means of cam tracks 24 and 25providedjon an attachment 26 of said post and through the agency ofbell-crank levers 27 which are fulcrumed to lugs 27 provided on thecarrier hub 7. One of the arms of a lever' is provided with aroller'which engages said cam track while the other arm is connected tothe former-by a lifting-rod 28. 1

Supplementary to the cam' track 25 whic is employed to lower the formermembers, I

provided respectively upon the former member and the Jnatrix to-positivelyhold these parts-in V tive positions to overcome theseparation of the same due vto the expansion of the matetheir properrela are supplied with batter use a pair of trackways, 29 .and 30, toengage lugs 29 and, 30

rial in the early stages ofcooking, through the generation of steam orotherwise. Below the molds is'a pluralit of perforated pipes 31 whichserve as gasu'rners.

Above each of the former members is a gas burner comprising a pipe 32fixedly secured thereto and having at its underside a series of holesarranged todirect flames into the; various subjacent cores 23. The pipes32 are each connected by a hose 33, or

an equivalent, with. outlet openings provided in the peripheral wall ofa gas reservoir 34 which is connected with. the carrier for rotationtherewith.

35 represents a' gas supply pipe'extending through a stufiing box 36into said reservoir. Secured to each former member is a sheet metal hoodconsisting of a substantially semi-cylindrical centralpart 37 affordinga- 20 coverfor a former member, and with two downwardly inclined wings37 extending from the lower edges of the part 37 at opposite sides. Inproximity to the hood part 37 each of the Wings is provided withapertures 38 which' serve as outlet openings forthe hpt combustion'gasesderiji'd from the burners 31. Bysuch devices t e matrices of themolds-are subjected to a relatively high degree of heat by reason of thecurrents of hot air and gases being directed close 'to the same inflowing to 'the ape-r tures to escape therethrough.

'The batter feeding. devices for the machine will now be described. Thebatter is supplied to a hopper 40, Fig. 1, whence,= it flows into achamber 41 provided in a branch '42 ,of the hopper edestal 43. Saidbranch extends radially oi the machine into the space between the matrixand former members when the former memberis in the elevated position inwhich it isrepre- 'sented. at the left of Fig. 1. Depending from said'arm are cylindrical vessels 44 arranged with theiraxcs parallel andatright angles to a plane radial of the machine. These vessels areprovided with in tion within each of the vessels 44 is a circulet ports45 communicating with the chamber 41 above, and with discharge ports 46.below, for the respective'recesses of the mold matrices. Fitted foroscillatory molar hollow valve 49 having ports 47 and 48 'pivotallysupported upon a a 53 and53', whereof the lower one is driven bysuitable power transmission the other shaft member is operaitivelflcdnenected thereto by a clutch-coupling To discharge the batter I utilize ineach of. the valves a iston 56, see Fig. 3, havin a rod 57 ex'ten ingthrough the valve en 49 and connected to a cross head 58 which is alsoconnected to arms 59 of bell-cranks whose other arms 59 are connected toa drag bar 60. 61 is a link connecti'ng'this drag bar with a lever 62pivotally connected" by a pin 6 to the bracket 52. The lever 62 cured tothe shaft 53 is a cam toe..55'which'. successively engages the arms 51ai1'd 51'- The is provid with arms 62 and 62 disposed as illustr ted inFig. 2'and an arm 64 is.

pivotally connected to the pin 63. The rm.

64 is, in adjustzzgly held in operative position throug the medium of ascrew 65 extend ifect, a part of the lever 62 and is 'ing thiough athreaded 'hole in the leverarm 6 A cam toe 66 is carried on the shaft ;3and is arra'ngedto alternately engage the arms-64 and 62 to affordvibratory movements to the lever 62 whereby the pistons 56 are movedtoward and from the ports of the various valves. When the too 66 engagesthe'arm 64 the pistons are impelled away -from.the ports to induce allowof the batter to within the valves, but when the other arm 62is thusengaged contrary motion is imparted to pistons resulting in the positiyeejection of the batter from the valves through the then coinciding ports46 and 48 to supply the molds with batter. Ba

adjusting the screw 65 the amount of fee is-regulated tocorrespond'with' the travel of the pistons. a The operation of theinvention will, it is thought, description.

What I claim as new, is-

1: In an ice cream cone cooking apparatus, a vertically. movable former,heatin cores upon said former, a hood over said former, projecting inclined wings upon said hood extending below the plane of the open tops'ofsaid cores and p'rovided'with rows of outlet apertures adjacent to thehood.

2. An ice cream cone cooking apparatus comprising a standard, a formerand a gas reservoir revolubly-mounted upon said standard, hollow coresupon said former, a

gas burner pipe upon said former provided with openings adapted fordirecting flame e understood from the foregoing.

separately into each of said eores, a hose connection between said pipeand'reservoir, a stationary gas entrance plpe entering said gasreservoir, a sheet metal hood mounted over said former,downwardly-inclined Win s extending from-the lower edgesof. the bed andprovided with rows of outlet apertures adjacent to the hood and the saidformer member being readily movable vertically. .10
